I would suggest the following schedule:
Draft 2HG.
Standard,
Modern
Draft
Standard 2HG
every time before a standard event I'd put a draft, maybe some of the cards drafted will help to build the standard deck for the following week. Furhermore, I think that every 3rd week we should schedule a modern event.
After we finish the boosters for draft I suggest to replace it with block constructed / pauper / peasant etc.
I'm in for the EDH side. Maybe we should sanction 3 events/week, given the fact that every sunday we have Legacy.
